mysql数据库添加用户及分配权限具体实现

insert into mysql.user(Host,User,Password) values("localhost","phplamp",password("1234"));//创建用户
grant all privileges on dbname.* to username@% identified by password;//创建用户并分配所有权限
grant select,update on phplampDB.* to phplamp@localhost identified by 1234;//创建用户并分配权限
update mysql.user set password=password(新密码) where User="phplamp" and Host="localhost";//修改用户密码
--删除用户指定权限
revoke insert,update,delete,select ON *.* from xbb@localhost IDENTIFIED BY 123;
